IntroductionCurrently, the Philippines is facing power crisis. Through the use of various technologies including such unconventional resources as wind and solar energy they were able to supply power to cities and towns. But civilizing rural places reduces the sources of power. The more houses are good but the more they have, the more electricity is consumed. Now, consuming too much energy affects the expenses of the government though there are a lot of sources of energy in the Philippines. A power crisis results to shutting down factories and small businesses. Also homes in metro centers would have to endure brownouts that lasted for as long as ten hours a day due to the big insufficiency supply. Even large companies had to reduce working hours, or worse, shut down temporarily, despite their purchase of their own generator sets. Having known this situation, it is really needed for alternative and other sources of power that we could use in the coming times.

A. Background of the Study The researcher, as one of the consumers of the electricity, also experiences the power crisis. Due to different factors that results to sudden brownouts especially those in the province, the researcher came up with the study entitled “Potato Battery”. Two new sources are fruits and vegetables. These are organic and can easily be bought at farms and markets. One of these is the use of potato but not all fruits and vegetables are usable. Potato had been considered due to it’s high content of phosphoric acid.

B. Statement of the problem
This study basically aims to find out whether a potato could be able to produce enough power to light up a bulb. And if it does, how many potatoes would be needed in order to do so.
C. Scope and Limitations
This study aimed to answer the following questions;
1. Will the potato be able to generate power that could light up an LED bulb? 2. How many potatoes would be needed in order to make an LED bulb light?...

POTATO INTO BATTERY
Abstract
a.Purpose
To lessen the consume of electric charge
b. Procedure
We insert copper and zinc electrodes in to the potato, close but not touching each other. We use Clip leads to connect our electrodes to the Multimeter to measure voltage between two electrodes or current passing through the multimeter. For this experiment we used a galvanized nail for our Zinc electrode.
c. Result
It did go well and thepotato did give voltage to the equipment (clock) However, the energy needed depends on the potato also the voltage is not permanent for the potatoe’s voltage also runs out in a time period.
d. Conclusions
therefore potato is an effective source of voltage and it can lessen the consume of electric charge however it also depends in the potato.

"Review of Related Literature and Studies"
Presented in chapter is a synthesis of research that supports the evaluation and explains the importance and advantages in using the potato-powered battery. Many questions about potato-powered battery are explained in this study. Thus, this study is a complete overview about potato-powered battery.

Two metals – an anode, which is the negative electrode, such as zinc, and a cathode, the positively charged electrode, such as copper. The acid inside the potato forms a chemical reaction with the zinc and copper, and when the electrons flow from one material to another, energy is released. (Galvani, 1780)
The potato serves as a solid state salt bridge. The advantage is in the convenience of a solid component with a naturally generated composition. The quantity of potatoes needed for the salt bridge function is negligible relative to food consumption. The wearable material is the Zn. In fact with proper studies it may turn out that the migration of Zn ions into the potato may provide nutritional benefits to the potato slice used in the battery. Therefore no food is wasted. Furthermore, as mentioned in the paper, while the potato may be optimal because it is widely available, every tuber or solid plant material could be used as...

Research Project: Potato
The potato originated in the South American Andes, but its heartland of wild genetic diversity reaches from Venezuela, Colombia, Ecuador, Peru, Bolivia, Argentina, Chile, Uruguay, Paraguay, southern Brazil, northward into Central America, Mexico, and the southwestern United States. Potato was first cultivated between 3 and 7 thousand years ago, some scientists believe they may have grown wild in the region as long as 13,000 years ago. Potato is the third most important food crop in the world after rice and wheat in terms of human consumption. More than a billion people worldwide eat potato, and global total crop production exceeds 300 million metric tons. Located in Lima, Peru The international potato center maintains the largest collection of potatoes in the world, including more than 7,000 accessions of native, wild, and improved varieties. Potatoes can grow from sea level up to 4,700 meters above sea level from southern Chile to Greenland. Potatoes are produced in over 100 countries worldwide. Potato is vegetative propagated, meaning that a new plant can be grown from a potato or piece of potato, called a “seed”. The new plant can produce 5 through 20 new tubers, which will be genetic clones of the mother seed plant. Potato plants also produce flowers and berries that contain 100-400 botanical seeds....

...Make a Battery from Potato
Introduction:
Batteries generate electricity through a chemical reaction between two different electrodes and one electrolyte. Use of Copper and Zinc electrodes and Sulfuric acid as electrolyte is a proven method for this process. We are wondering if we can use any other liquid as electrolyte? This gave us the idea of using a potato as electrolyte. After all a fresh potato has a lot of juice that may serve our purpose as electrolyte.
Problem:
Can Potato be used to generate electricity?
Hypothesis:
Potato juice contains many water soluble chemicals that may cause a chemical reaction with one or both of our electrodes. So we may get some electricity from that.
Material:
For this experiment we use:
A fresh potato
Copper Electrode
Zinc Electrode
A Digital or Analog Multimeter to measure Voltage or Current of produced electricity.
Alligator clips/ Leads
Procedure:
We insert copper and zinc electrodes in to the potato, close but not touching each other. We use Clip leads to connect our electrodes to the Multimeter to measure voltage between two electrodes or current passing through the multimeter. For this experiment we removed the shell of a broken AA battery for our Zinc electrode. (Make sure to test your multimeter by connecting it's Positive and Negative wires to each...

Introduction:
Potatoes are just your average food; they have been around for as long as the human race can remember. In this lab we will make them be a prime example of osmosis, which is a transport mechanism. In this lab the problem being tested was what environment affects the mass of the potatoes the most. The independent variable is the environments used salt, water and iodine solution. The dependent variable is the mass of the potato after being exposed to the environment for 5 days. The control was a potato in no specific environment, meaning it is just sitting in air, no salt and no water/iodine solution. If the potato is exposed to a specific (hypotonic/hypertonic) environment then the mass will increase/decrease because the cell will grow or shrink due to the environment exposed to.
Experimental Design:
The groups being testes are the hypotonic environment (water and iodine), hypertonic environment (Salt) and the control which is just the potato in just the beaker. The time the potatoes stay in each environment is 5 days. One potato is in 300mL of water and iodine solution, another is in 300mL of salt and the last potato is just in air. The potatoes are all fully peeled with no skin. The potatoes are in 3 different beakers with saran wrap over the top of each beaker.
Materials:
